摘要
东方汽轮机厂３００ Ｍ Ｗ 汽轮机电液并存型中压抗燃油调节系统，在潍坊１ 号机大修中改为高压抗燃油全电调系统并获得了甩负荷试验的成功。介绍和分析了同类机组的改造前后甩负荷试验情况，并对机组的动态特性作出了评价。
The control system of 300MW steam turbine which originally was a combined hydraulic and digital electrohydraulic(DEH) control system with intermediate pressure fire-resistant liquid,has been retrofitted into a DEH system with high pressure fire-resistant liquid.Load rejection test has been carried out to verify the dynamic performance of the unit after retrofit.This paper analyzes the test result and gives out appraisa.
